This application is a continuation-in-part of copending application Ser. No. 054,775 filed July 5, 1979, which is a divisional of copending application Ser. No. 861,916 filed Dec. 19, 1977, and now U.S. Pat. No. 4,179,403.

FIELD OF THE INVENTION

This invention relates to a process of hydrogenating unsaturated hydrocarbons using a catalyst comprising an ion exchange resin with a ligand ionically bounded thereto and with the ligand coordinately bonded to ruthenium, rhodium, palladium, osmium, iridium or platinum.

BACKGROUND OF THE INVENTION

The use of heterogeneous catalysts over homogeneous catalysts has several advantages such as allowing the use of fixed beds, ease of separation of catalyst from the product and catalyst recovery and regeneration.

Traditionally, to produce heterogeneous catalysts from metals of the transition element series, these metals have been deposited on inert supports such as alumina or silica. More recently metal catalysts have been covalently attached to inert resin backbones by use of diphenylphosphine or other ligands which are attached directly to the polymer and coordinately bonded to the metal. Typical examples of this type are found in U.S. Pat. No. 3,998,864, issued Dec. 21, 1976, and in Pittman et al, Chemtech, p. 560-566, 1973.

In the composition of the invention, on the other hand, the metal is coordinately bound to a ligand and the ligand is ionically bound to an ion exchange resin. Some of the advantages of the materials of the invention are that the materials are relatively simple to prepare using commercially available compounds, the preparations involve no exotic conditions, and often times may be carried out in an aqueous solvent system and the resins may be easily stripped of metal and ligands for isolation of the metal species and regeneration of the catalyst. The resin based catalysts of this invention have unique selectivity-reactivity properties when compared to their homogeneous analogues.

SUMMARY OF THE INVENTION

This invention provides a process for hydrogenating with hydrogen, unsaturated hydrocarbons to less unsaturated hydrocarbons. This process comprises contacting the unsaturated hydrocarbon and hydrogen with a catalyst comprising (a) an ion exchange resin, (b) a transition metal selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum. The catalysts have unique selectivity-reactivity properties when compared to their homogeneous analogues and can easily be stripped of their expensive metal component and readily regenerated for future use. The catalysts are particularly suited for the reduction of olefinic bonds.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The catalysts described herein are used to hydrogenate with hydrogen hydrocarbons containing unsaturated carbon bonds. The unsaturated carbon bonds which may be hydrogenated by the process of this invention include olefinic and acetylenic, unsaturated bonds such as ##STR1## etc. may likewise be hydrogenated in the process of the instant invention. The process is particularly suitable for the hydrogenation under mild conditions of hydrogenatable organic materials having carbon-to-carbon unsaturation such as acyclic monoolefins and polyolefins, cyclic monoolefins and polyolefins and mixtures thereof. These materials may be unsubstituted or substituted with additional non-reactive functional groups such as halogens, ether linkages or cyano groups. Exemplary of the types of carbon-to-carbon compounds useful herein are hydrocarbons of 2 to about 30 carbon atoms, e.g., olefinic compounds selected from acyclic and cyclic mono-, di- and triolefins. The catalysts of this invention are also suitable for hydrogenating carbon-to-carbon unsaturation in polymeric materials, for example, in removing unsaturation from butadiene polymers and co-polymers such as styrene-butadiene-styrene.

The hydrogenation reactions herein are normally accomplished at temperatures from about 40° C. to about 160° C., preferably from about 60° C. to about 150° C. Different substrates being hydrogenated will require different optimum temperatures which can readily be determined by routine experimentation. The initial hydrogenation pressures may range up to about 3,000 psi partial pressure, at least part of which is present due to the hydrogen, or above. Thus, pressures from about 1-500 atmosphere are suitable. More particularly, pressures up to about 2000 psig and preferably from about 100-1000 psig are employed. The reactive conditions are determined by the particular choice of reactants and catalysts. The process may be either batch or continuous. In a batch process reaction times may vary widely, say between about 0.01-10 hours or higher. In a continuous process, reaction times may vary between about 0.1 seconds and about 120 minutes, preferably between 0.1 second and 10 minutes.

The ratio of catalyst to material being hydrogenated is generally not critical and may vary widely within the scope of the invention. Molar ratios of catalyst to material being hydrogenated between about 1:1000 and about 10:1 are found to be satisfactory; higher and lower ratios, however, being within the scope of the invention.

If desired, the process may be carried out in the presence of an inert diluent, for example a paraffinic or cycloparaffinic hydrocarbon.

The ion exchange resins utilized to prepare the composition utilized in this invention are well known in the art and are readily available commercially. These are in the gel form or are macroporous and are either strongly acidic, weakly acidic, strongly basic, intermediate basic, weakly basic or mixed acid-base. The strong acid resins typically have base resins of cross-linked styrene, styrene-divinylbenzene, phenol-formaldehydes, benzene-formaldehyde, having functional sulfonic or phosphonic acid groups attached thereto. Also suitable are the fluorinated alkyl sulfonic acid resins containing the --CFSO₃ H group as, for example, the NAFION® type resins supplied by E. I. DuPont De Nemours. The weak acid resins are those with carboxylic acid groups and are typically acrylic acid derivatives such as, for example, those resins prepared by the copolymerization of methacrylic acid and divinylbenzene. Another weak acid resin is the chelating type which is a styrene-divinylbenzene copolymer containing aminodiacetic acid functional groups which can serve as an anion exchanger at very low pH. The basic resins typically have base resins of cross-linked styrene-divinylbenzene, phenolformaldehydes, benzene-formaldehyde, epoxypolyamine, phenolicpolyamine having functional amine, either primary, secondary, tertiary or quaternary, or pyridinium groups attached thereto. Typical examples of suitable commercially supplied resins are given in Table I (reference: Bio-Rad Laboratories Catalogue, Chromatography, Electrophoresis, Immunochemistry and Membrane Filtration, Price List C, March 1977, p. 11).

The preferred resin choice for the composition used in this invention will depend on the particular ionically bondable moiety utilized on the linking compound as well as on the particular use envisioned for the composition. For example, if the composition were used in liquid-phase catalysis, the composition and pH of the liquid would determine the preferred resin to be utilized.

The linking compound is hydrocarbyl, i.e., alkyl, aryl, or mixtures of aryl and alkyl components, which can be either cyclic or acyclic or mixtures thereof containing from 1 to about 100 carbon atoms, preferably from about 3 to about 80 carbon atoms and has at least two moieties containing an atom other than carbon.

At least one moiety is in the ionic or ionizable form and is compatible with the exchange group on the ion exchange resin, i.e., when the exchange group is acidic, the resin-compatible ionic moiety on the linking compound is basic-derived and vice versa. The acidic-derived resin compatible ion moiety is derived from carboxylic acid (RCO₂ ⁻), phosphonic acid (RPO(OH)O⁻), phosphinic acid (R₂ POO⁻), sulfenic acid (RSO⁻), sulfinic acid (RSOO⁻), sulfonic acid (RSO₂ O⁻), boronic acid (RB(OH)O⁻), boronous acid (RBO⁻). The basic-derived resin compatible ion moiety is monohydrocarbyl ammonium (RN⁺ H₃), dihydrocarbyl ammonium (R₂ N⁺ H₂), trihydrocarbyl ammonium (R₃ N⁺ H), quaternary ammonium, (R₄ N⁺), pyridinium (RC₅ H₄ N⁺ R₁), phosphonium (R₄ P⁺), arsonium (R₄ As⁺), and sulfonium (R₃ S⁺).

The linking compound may have more than one of the ionic moeties. It may be polyfunctional, for example, in carboxylate ion, in phosphonate ion, in sulfonate ion, in quaternary ammonium ion, in pyridinium and the like. The polyfunctional group may be the same or different.

At least one other moiety of the linking compound has an atom capable of complexing with metals from the transition element series, and consists of trivalent nitrogen, trivalent phosphorus, trivalent arsenic, trivalent bismuth, and trivalent antimony.

The three valences of the complexing atoms may be satisfied by any organic radical; saturated or unsaturated aliphatic, and/or saturated or unsaturated heterocyclic and/or aromatic radicals. The radicals may contain any functional group such as carbonyl, nitro, and hydroxy groups as well as saturated and unsaturated alkyl groups as well as saturated and unsaturated alkyl groups and the radical may be bonded to the complexing atom directly through a carbon-complexing atom linkage or through an electronegative atom such as oxygen or sulfur.

It is also suitable for a simple organic radical to satisfy more than one of the valence of the complexing atoms, thereby forming a heterocyclic compound with the trivalent complexing atom. For example, an alkylene radical may satisfy two of the valences thereby forming a cyclic compound. Another example would be the alkylene dioxy radical to form a cyclic compound where oxygen atoms link an alkylene radical to the complexing atom. In these two examples the third valence may be satisfied by any other organic radical.

The linking compound may have more than one of the metal-complexing moieties. It may be, for example, polydentate in phosphorus atom, e.g., it may be bi- or tridentate, having two or three phosphorus atoms. It may have mixed complexing atoms, e.g., a phosphorus and arsenic atom or two phosphorus atoms and one nitrogen atom, etc.

The trivalent nitrogen atom will be present as an amine, i.e., as a primary, secondary, tertiary amine or as pyridine or cyanide. The trivalent phosphorus will be present as phosphine (R₃ P), phosphinite (ROPR₂), phosphonite ((RO)₂ PR) and phosphite (RO₃ P). Correspondingly, trivalent arsenic will be available as arsine, arsinite, arsonite and arsenite, trivalent bismuth as bismuthine, bismuthinite, bismuthonite and bismuthite; and trivalent antimony as stibine, stibinite, stibonite and stibite. The preferred complexing atoms are phosphorus and nitrogen. The tertiary amines, phosphines, arsines and stibines and bismuthines have a marked tendency to form nonionic complexes with metals.

When the linking compound is polydentate in an ionizable heteroatom, it is understood that there will be a statistical distribution of the ionized atoms upon quaternization or protonation. For example, if one mole of a linking compound which contains 3 amine groups is protonated with 2 moles of HCl, then some of the molecules of the linking compound will have 3 quaternized amines groups, some will have 2 and some will have 1, but on the average there will be 2 quaternized amino groups per molecule. It is further understood from general principles of organic chemistry that unit charges resulting from quaternization and protonation can be distributed as partial charges over several heteroatoms in a linking compound molecule.

Thus the linking compound as reacted in the composition used in this invention will have at least one protonized or quaternized heteroatom and at least one heteroatom complexed with a transition element metal. Suitable linking compounds utilized in making the composition used in the invention include but are not limited to the following examples:

tris(dimethylamino)phosphine

tris(diethylamino)phosphine

tris(diisopropylamino)phosphine

tris(methylethylamino)phosphine

tris(p-dimethylaminophenyl)phosphine

tris(p-diethylaminophenyl)phosphine

tris(p-methylethylaminophenyl)phosphine

tris(o-dimethylaminophenyl)phosphine

tris(m-dimethylaminophenyl)phosphine

tris(dimethylaminoethyl)phosphine

tris(dimethylaminoethyl)phosphite

ethylbis(diphenylphosphinoethyl)amine.

Substitution of phosphinites, phosphonites, phosphites for the phosphine in the above compounds as well as arsines, arsinites, arsonites, arsenites, bismuthenes, bismuthinites, bismuthonites, bismuthites, stibines, stibinites, stibonites, stibites and amines produces linking compounds useful in preparing the composition used in this invention. Other suitable compounds are:

tris(4-N,N-dimethylaminophenyl)phophine

2-(P,P-diphenylphosphino)benzoic acid

tris(beta-aminoethyl)amine

2-chloronicotinic acid, and 2-carboxypyridine

1,1-dimethyl-4-phenylpiperazinium salt

2,2'-alkylarsino-1,1'-diphenylamine

2-(P,P-dicyclohexylphosphino)benzoic acid

beta-(dicyclohexylphosphino)propionic acid

1,4-(P,P-diphenylphosphino)benzene

2-diphenylphosphino-3-carboxy-2-butene

2-(P,P-diphenylphosphino)benzene sulfonic acid

2-amino-s-triazine

1-diphenylphosphino-2-diphenylphosphinoethane

tris-(beta-N,N-diarylaminoethyl)phosphite

tris(N,N-diarylamino)phosphine

bis-(beta-diphenylphosphinoethyl)ethylamine

3-(dialkylphosphino)benzene phosphonic acid.

Thus the organic linking compound is hydrocarbyl with at least one moiety capable of coordinate bonding and at least one moiety capable of ionic bonding. The primary limitation on the organic linking compound is a functional one, i.e., one moiety must be capable of coordinate bonding and the other moiety must be capable of ionic bonding. These moieties are well known to those skilled in the art.

The metals or metallic elements complexed with the linking compound are selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium, platinum & mixtures thereof. As used herein the term "metal" refers to a "metal bonded coordinately" to the linking compound. Thus, as used herein, metal refers to a metallic compound rather than the metal which is found, for example, in a silver dollar.

The complexed metals can be in various oxidation states. See "Complexes of the Transition Metals with Phosphines, Arsines and Stibines", by G. Booth, Adv. Inorg. Nucl. Chem., 6, 1-69 (1964) for a comprehensive description of complexes. For example, the Booth reference cites the following oxidation states for metals complexed with phosphines.

ILLUSTRATIVE EMBODIMENTS

The catalyst preparation procedures described below were carried out in nitrogen-filled dry boxes. The solvent benzene was purified by distillation over CaH₂, all other solvents were of reagentgrade and used as supplied. The metal complexes [Rh(CO)₂ Cl]₂, Rh(PPh₃)₃ --Cl, Rh(NO₃)₃ in H₂ O, Ru(PPh₃)₃ Cl₂, PtCl₂ (PPh₃)₂, [PtCl₂ (PBu₃)]₂, Pd(C₆ H₅ CN)₂ --Cl₂, PdCl₂ (PPh₃)₂, [Pd(allyl)Cl]₂ and Pd(OAc)₂, and compounds CH₃ Br, SnCl₂.2H₂ O, isonicotinic acid, and phosphines [(CH₃)₂ N]₃ P,[(CH₃)₂ NC₆ H₄ ]₃ P, [(CH₃)₂ NCH₂ CH₂ O]₃ P were used as supplied. The quaternized aminophosphines were prepared by the reaction of 1 equivalent of CH₃ Br with an aminophosphine in toluene solution at room temperature. The quaternized aminophosphine precipitated readily from the toluene solution. The complex Ru(CO)₃ (PPh₃)₂ (J. Chem. Soc. Dalton, 399 (1976)), PtH(SnCl₃)(PPh₃)₂ and PtH(SnCl₃)(CO)(PPh₃)₂ (J. Am. Chem. Soc. 97 3553 (1975)) were prepared as described in the references. The resins are indicated by (resin backbone)-(exchange group), e.g. a sulfonated styrene divinylbenzene resin would be (styrene-divinylbenzene)-(SO₃ ⁻), etc. Ph, C₆ H₅ and φ are used as abbreviations for phenyl; --φ-- and C₆ H₄ indicates p-substitued benzene moieties.

The mixture was then stirred magnetically from the side of the flask for 48 hours to prevent resin attrition. The resin was filtered by suction, washed with 3×50 ml of acetone, and dried in a vacuum oven (50° C.) overnight.
